Well I guess we are just going to have to disagree over this but then I only have 25 years experience within the industry and have seen the current demise of the way horses are now ridden. Don't forget lads used to arrive in a yard and they became apprentices to that trainer for 5 years. They were trained by the head lad and senior lads on their riding skills as well as looking after their charges. When I first started riding racehorses, I was a fair rider having hunted/Pony Clubbed most of my life. It is a completely different way of riding and I had loads to learn, and was taught by some very good lads. Initially how to hold a horse that took a hold and then learning to balance it and educate a young horse. Its not just a question of sitting on the thing, steering and pulling on the reins when you want to stop. I can now tell you what sort of ground a horse will act best on, whether it is well-enough balanced to handle somewhere like Epsom or Brighton, what its ultimate trip should be. You have to teach a horse to listen to its jockey so that it will settle and not burn up energy. Ever wondered why some trainers horses always pull? Probably because the staff at home are not good enough. OK some horses will always get lit up on a racecourse, but the trainer should know his staff well enough to put the right lad on to settle it/keep its mind on the job.
I can go on forever but have a read of this book:

Its dated but a very good book.
